Document Filter Error Handling

[AayushTyagi1]

When we try to apply document filter on a document which does not have indexes.
It directly throws error and the extension crashes afterwards.

When we try to remove a collection with document filter and then try to create a collection, application crashes

Another test case which we should test but due to crash I could not test is
When we create a document filter on a collection say x and we remove it and we again create that collection x, it should not have that document filter i.e. filter should be removed from the memory.
