bitbake: toaster/tests/functiona/project_page: Improve waits and drop polling

These changes:

* Drop the poll parameters
* Add waits where needed or make them more specific
* Add calls to close notification boxes since they can obscure
  other page elements
* In one case wait for a "Loading" message to be replaced

(Bitbake rev: 2bde969486a4761fa0e6f9590c9fa08d385666b1)
