Fix small rotation bugs

If some renderer has not null rotation, but for some reasons this
rotation wasn't applied, iText was failing with exception trying to
restore not saved graphic state, because of missing check.
RotationUtils#retrieveRotatedLayoutWidth was returning full element
width, but is expecting to return only content width.
Also corresponding tests where added, and already done TODO was
removed

Autoported commit.
