waggle dance with regex mapped-databases error

[Hongyan He]

The situation is that, i hve two metatores, one named a which is the primary metastore, the other is b which is the federation, and both of them have same database called ssb, i use regex in a with   mapped-databases : ^(?!.*?ssb).*$ and in b with  mapped-databases : ssb,  but when i use show database, it display ssb twice，the result is:

default,ssb,ssb, is it a bug?

regex looks ok, I checked that with the code I think it should match as you expect.

If they get the same name it should throw this exception: https://github.com/ExpediaGroup/waggle-dance/blob/main/waggle-dance-core/src/main/java/com/hotels/bdp/waggledance/mapping/service/impl/StaticDatabaseMappingService.java#L185

So not sure what's going that it doesn't trigger. Best to raise an issue in the github repo if possible with a failing unit test.

Thanks,
