COMPAT: remove pandas line_width/height deprecations from test suite

[jreback]

https://travis-ci.org/jreback/pandas/jobs/23875619

if deprecations mode is turned on #6960 then these become apparant

I think the tests simply need to be change and/or asserted that these are actually producing deprecation warnings

[jreback]

@jorisvandenbossche a couple of minor sql deprecation warnings that should prob be caught / tested

[jreback]

ok...almost all warnings gone (and those that remain) are 'ok'
