Fix NPE at TableMetadata.equals()
TableMetadata.equals() throws a NPE if its options could not be parsed.
Due to incorrect parsing of some table options (we don't have information about which option failed – will open a separate ticket if we have that information later).
Note: already fixed in 3.0.x, should not be merged.
Btw is it possible to have the CREATE TABLE statement that originated the NPE? Thanks!
