Don't panic in turbine with no classes
ALLOW_MISSING_DEPENDENCIES=true can cause missing dependencies to be
hidden from GenerateAndroidBuildActions, which is triggering the
len(jars) == 0 check in compileJavaHeader. For the
ALLOW_MISSING_DEPENDENCIES=true case the check is unnecessary, as the
build rules will be replaced with runtime errors. On the off chance
the check would have been hit in a real build, allow merge_zips to
create an empty zip file if it is asked to.
Test: m ALLOW_MISSING_DEPENDENCIES=true
