Subject: Show hint instead of auto-populating timepicker.

Textboxes will now show hint text if not set rather than populating
text. Also changed validation text to have similar behaviour to the
radial setter.

Change-Id: I8ce55d7d7898be9b0a842d3f1f9a2e8deb01f5b3
Test: manually https://drive.google.com/file/d/1bD_dbIF9dgOr1B3EuSMBlJY9M97Z19vc/view?usp=sharing
