Unable to add tables to rename aliases twice on Export

[ChrisHSandN]

Describe the bug

The rename exported... checkbox on the export tab fails to do anything.

To Reproduce

Steps to reproduce the behavior:

1. Go to any table with rows e.g. mysql.db
2. Click on the Export tab
   Export Method: Custom - display all possible options
   Format: SQL
   Output: Rename exported databases/tables/columns
3. Enter anything into "Select database" and "Select Table"
4. Save And Close

Rename exported databases/tables/columns checkbox remains unticked (and is impossible to tick). While exported SQL file does not use the new table/database names.

Expected behavior

Rename exported databases/tables/columns checkbox should be checked after saving and the output SQL file should have the given names for db and table.

Hi @ChrisHSandN
On the steps to follow you did no say to click on "Add", did you do it ?

Hi @williamdes,

The server I initially found this bug on was a 5.0.1 and it seems the Add buttons were broken on that release - so when I re-tested it on your 5.0.5-dev sever I just assumed you didn't need to press Add when setting a db/table alias 🤦‍♂️. Going back and pressing "Add" it works as expected.

Closing, sorry for wasting your time and thanks for your prompt responses.

One thing that I noticed while reproducing this was that the add buttons worked only once. If you close the modal, open it again, remove the rows and then try again to add the names, it won't happen. So I've fixed that issue in the above PR.

I can confirm that, thank you !
Merging your fix, it works great
