pgAdmin 4 commit: Feature test fixes:

Feature test fixes:

The query tool element while running on jenkins, is present on the DOM but not visible due to comparatively small page
size.So handle it , would work in both cases(if element is visible or not). 
The tab name handles XSS characters due to which table name <h1> is shown modified accordingly in the tab name.
