@khalilcader any other repro steps?

@sczs If it's not easy to reproduce, assign this to testing to see if they can repro on one of their devices.

I can repro this no problem. Thanks Gabe, Khalil!

[ios] Fixes TableViewTextItem text color assignment.

TextItemColorBlack was being used as the default color even if
textColor was not being set. This was causing the item label
to skip the styler textColor for the label. This CL fixes that
problem and introduces some unit_tests to check this.

I've verified this issue on Canary, so we should be ready to cherrypick.

Approved!
