Don't call property getters during initialization.

Fixes: 274967902

A robustness was added to AnimatorSet initialization where
property values could be queried while initializing an
AnimatorSet so that it could handle an edge case where AnimatorSets had
cross-talk in their child animators (two sets playing together
have childr animators that animate the same value). However,
some clients will crash when a property value is requested during
the initialization, so that feature was rolled back.

Test: new test, existing animation CTS and APCT
