[issue20792] IDLE: Extend tests for PathBrowser

[Saimadhav Heblikar]

New submission from Saimadhav Heblikar:

This patch does 
1.Remove pep8 violations in PathBrowser.py . Replaces "file","dir","sorted" by "file_","dir_","sorted_" respectively.
2.Extends test coverage for PathBrowser.py in idle_test/test_PathBrowser.py

New modules now under tests include
1.dirBrowserTreeItem - getText,ispackagedir
2.pathBrowserTreeItem - getText,getSublist

Only method missing a test after this patch will be listmodules.I am not too sure whether it requires a test for itself.it is indirectly being tested from lines 8 and 9(in the current tip).
