Description:
After deleting a Firebird file that was connected to a Base database, the file is recreated when the Base document is opened again.

Steps to Reproduce:
To test this issue, it is needed an external Firebird database, so we will create a Firebird external database file (it is not needed to have Firebird server installed)

    1. Open Base
    2. Select Connect to an existing database
    3. In the dropdown list, select Firebird external. Click Next
    4. Click on Create new button
    5. In the Save as dialog, choose a suitable place and give a name to the Firebird database file, for example Test1.fdb. Click on Save, then Click Next
    6. In the Setup the user authentication step, do not change anything. Click Next
    7. In the Save and proceed step, click on No, do not register the database (it is not needed register).
    8. Click on Finish.
    9. Give a name to the Base .odb file, for example Test2.odb

Once the database file has been created, to see the issue:
    1. Close Base
    2. Delete the Firebird file Test1.fdb
    3. Open the Base file Test2.odb
    4. Go to the Tables area
    5. Observe that has been created a new Firebird file called Test1.fdb in the original place where the old .fdb file was deleted

Moreover:
    6. Open Test2.odb
    7. Go to menu Edit > Database > Properties
    8. In General section, it is shown the path of the firebird file. Change the name of the file to other different, for example Test3.fdb
    9. Close Database Properties dialog
    10. Go to any other different area but Tables, return to the Tables area
    11. A new Firebird file named Test3.fdb has been created, although Test1.fdb hadn't been deleted

Actual Results:
A new file is created when reopen Base

Expected Results:
No file would be created
