Remove assert that blocks Realm

[nathandud]

Proposed fix to #621. A realm database table opens as expected when this NSParameterAssert is removed.

Can you see if just removing the && !databaseManager from the none condition part fixes it? I still want to keep the assertion, it just needs to be correct

rowIDs:(nullable NSArray<NSString *> *)rowIDs

It only works if removing rowIDs and !rowIDs from both all and none conditions

@lubelio the original issue states:

When opening up a SQLLite database table, the databaseManager points to null (and so do rowIDs and tableName) and the none condition is satisfied. However when trying to open a Realm database table, the databaseManager object pointer is not null and the assert fails. When I remove that assert, the code works as expected and I can view a Realm database.

If this is accurate, then simply removing the databaseManager from each check would suffice. The resulting condition would be:

!rowIDs && !tableName &&

And this would satisfy Realm, since those are both still nil. Right?
