#3828: pygrass.gis.Region.from_* should raise a ValueError if the specified map
does not exist.

I think it would be better if
{{{
pygrass.gis.Region.from_rast(raster_name)
pygrass.gis.Region.from_vect(vector_name)
}}}
would raise a {{{ValueError}}} if the specified map name cannot be found.
With the current implementation, the region remains unchanged and you have
no clue about that:
https://grass.osgeo.org/grass77/manuals/libpython/_modules/pygrass/gis/region.html#Region.from_rast
Note, it might make sense to raise the Exception from within
{{{get_mapset_raster()}}} but that function is used in more places and I
haven't checked if this will break anything.
