#4375 (ok 4.1.14) Group two DB, one's name is the prefix of the other one

[Hugues Peccatte]

When you create 2 DB:
- my
- my_test

I expect to have a group "my" with children:
- my
- my_test

But there is no group and both DB are displayed at first level.

If another DB my_<something> is created, they are grouped.</something>
