[QGIS-Developer] ~/.local/share populated with QGIS files for each test

[Sandro Santilli]

I found out that my `ctest` runs, under QGIS build dir, result
in a directory created under ~/.local/share/ having the same
name as the source python script the run test is coming from.

Hundreds of such directories.

Is this expected or is it a problem with my setup ?
