uic: standardize property lookups on QHash::value()

Browse Source 
This is the pattern used throughout the rest of the uic codebase,
and is both more efficient (one lookup instead of two with an
additional contains() call) and will allow porting to another
container.

In writeSpacerItem(), also gently optimize string handling.
