[pgAdmin4][Patch]: Fix the Domain Create dialog issue

[Murtuza Zabuawala]

Hi,

PFA minor patch to fix two issues,

1) Domain's Create/Properties dialog do not open due to JS error.
- Global variable issue.

2) Security label control's label font size issue.
- Backgrid adds backbone model id(which is 'label' in our case) in as a
class in <th> tag causing font size class collision with Bootstrap's label
class.
