  Fix valid location check, sync with other functions (#1777)

* This fixes the path join code in valid location check, i.e., fixes 94bcea4216cdabcd18dbe5dc4686e38d4d3800de (#1715 ).
* In the new 1-or-3 parameter interface, path to database was dropped when constructing the full path to the location.
* Creating mapsets from command line with -c now works again.
* Other validity and existence checks now use the same 1-or-3 parameter interface (path or db, loc, mapset).
* Tests added for modified functions and for couple of related ones.
* Import order fixed with isort not to have glob mixed GRASS imports as pointed out by Pylint.
* Two missing docstrings added to the is-current-x checks.
