Fix UITests that use File Open dialog to load documents

It relied upon the component being loaded before the next
Python code line is executed. OTOH, UITest.load_file uses
EventListener to wait for the OnLoad event, which should
be reused in all such cases.

This moves the waiting code to a dedicated context manager,
and modifies UITest.load_file to use it. Respective tests
using the File dialog also use the new manager to wrap the
action starting the loading process.
