ResourceModelTest index test fails, should disable _aliasOf criteria

[mdutoo]

The new alias feature makes ResourceModelTest's index test fail in OW Jenkins (but not on my machine, probably because of having a different MongoDB version ?):

Tests run: 10, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 3.493 sec <<< FAILURE!

=> allow LdpEntityQueryImpl to disable criteria on _aliasOf, only in test (and devmode):
