testing: use gunittest methods for temporary region, remove trailing whitespace

motivation for fix is actually a change of 'grass' from 'grass.script' back to 'grass' after 'import grass.gunittest' and subsequent error when acessing grass.script.use_temp_region (this is not a problem of gunittest, its import or Python, this shows how 'import grass.script as grass' is a bad practice)

moreover, grass.script.overwrite is a function, so assigning True does nothing (although the suggested API is interesting)
