Don't mark a WebMediaPlayer as idle until it has size and first frame.

Don't mark a WebMediaPlayer as idle until it has size and first frame.

Slow connections, large MediaSource appends, or open-in-background can
result in large delays from when the WMP is constructed until it reaches
a state appropriate for suspension.

Waiting until we have the first frame and size information to mark a
player as idle should resolve any issues around suspending too early.

BUG=592706
TEST=fixed unittests. Suspend does not occur w/ open-in-background.
