Sourcemaps seem to break when replacing "ngInject" prologues.

[derekdon]

I noticed if I use this loader to replace the "ngInject"; prologues my source maps no longer open the original file.

{
	loader: 'string-replace-loader',
	options: {
		multiple: [
			{
				search: /["']ngInject["'];*/,
				replace: '',
				flags: 'g'
			}
		]
	}
},
{
    loader: 'ng-annotate-loader'
},
{
	loader: 'babel-loader',
	options: {
		cacheDirectory: true
	}
},

Perhaps I'm missing something? If I take out the string-replace-loader source maps are okay again.

I have the same problem.
Currently this plugin breaks sourcemaps, but it should just leave them as it is.

@derekdon @Avol-V
which kind of sourcemaps do you use, folks? I guess, this issue is only about inline sourcemaps

[Avol-V]

No, I use external sourcemaps. There is a parts from my webpack.config.js:

	devtool: 'source-map',
	module: {
		rules: [
			{
				test: /\.tsx?$/,
				exclude: /node_modules/,
				use: [
					{
						loader: 'string-replace-loader',
						options: {
							search: /\b_import\(/g,
							replace: 'import(',
						},
					},
					{
						loader: 'ts-loader',
						options: {
							configFileName: './app/tsconfig.json',
						}
					},
				]
			}
		],
	},

Same to me.

devtool: "eval-source-map",

module: {
        rules: [
            // All files with a '.ts' or '.tsx' extension will be handled by 'awesome-typescript-loader'.
            {   test: /\.tsx?$/,
                // loaders: ["babel-loader", "ts-loader"],
                use: [
                    {
                        loader: 'string-replace-loader',
                        options: {
                            search: '_import\\(',
                            replace: 'import(',
                            flags: 'g'
                        }
                    },
                    {
                        loader: 'babel-loader'
                    },
                    {
                        loader: 'ts-loader'
                    },
                ],
                include: path.join(__dirname, 'src')
            }
      ]
}

@snipking I basically have the same setup like you. I hope my PR will fix this: #28.
