fix($httpParamSerializerJQLike): call functions as jQuery does

[gkalpak]

I'm submitting a ...

• bug report
• feature request
• other (Please do not submit support requests here (see above))

Current behavior:

Function properties are ignored by $httpParamSerializerJQLike().

Expected / new behavior:

Functions should be called and the return value used, the same way jQuery does.

(Although not necessarily a breaking change (in the sense that this serializer's purpose is to follow jQuery as close as possible), it may break some apps relying on the old, buggy behavior.)

@gkalpak Looking at this we could easily patch

angular.js/src/ng/http.js

Line 17 in 394dbcc

return v;

, but this would affect all other serializers. Is that something u want ?

[gkalpak]

No, we only want to affect $httpParamSerializerJQLike.
