Designer won't show ComboBoxes for onUpdate/onDelete-Behaviour when adding a constraint

[R-Klimkeit]

Describe the bug

After upgrading to the most recent version, I encoutered the problem, that the designer will not show up the ComboBoxes for the onUpdate/onDelete-Behaviour when adding a constraint anymore.

To Reproduce

Add a constraint in phpMyAdmin's Designer.
Even if both selected fields satisfy the requirement to be PRIMARY and INDEX, the ComboBoxes will get the wrong CSS-Property "display:none"

Expected behavior

ComboBoxes should get CSS-Property display="" if both selected fields fulfill the above mentioned requirement.

Client configuration

Reproduced with IE9 / Chome / FF

Additional context

There is a Datatype-mismatch-Error in "/js/designer/move.js" in line 1206 and 1214:

    j_tabs[db + '.' + T] !== '1'

must be

    j_tabs[db + '.' + T] !== 1

because the variable j_tabs does not hold string-values but integer-values (at least: anymore).
This change made me get rid of this bug.

@williamdes , Hey i reproduced the bug on my local server successfully and yes ensured that the bug can be fixed by changing (j_tabs[db + '.' + T] !== '1') to (j_tabs[db + '.' + T] !== 1) as it is holds some integer value as stated above. Shall I make the PR to fix it if you wish?
