Catch exception when parsing faulty AVD

If an application uses an animated vector drawable for its splashsreen
but the files generates an error (like a target not found for the
animation), we catch it and log it instead of crashing sysui

Test: manual, created an AVD with a <target> tag referencing a non
exising group in the dawable
