Account.get() does not work when multiple filters are provided with same key

[SargeKhan]

Expected behavior

If we run the command: Account.get([address: '1L}, {address: '2L'}]), it should return accounts with addresses 1L and 2L if both accounts exist in the database.

Actual behavior

Running the command: Account.get([address: '1L}, {address: '2L'}]) returns only 1 account even when both accounts exist in the database.

Which version(s) does this affect? (Environment, OS, etc...)

1.5.0
