Empty string as table name in TAP_SCHEMA.tables or columns prevents application to run

[gmella]

Ok this is not a normal situation however this may be improved to be ignored so the service is back again for valid tables ?

Anyway, this is more an opportunity to give a thanks for this nice tool.

Here is the stacktrace ;)
