localrepository: remove None as default value of path argument in __init__()

The path variable in localrepository.__init__() has a default value None. So
it gives us a option to create an object to localrespository class without
path variable. But things break if you try to do so. The second line in the
init which will be executed when we try to create a localrepository object
will call os.path.expandvars(path) which returns

TypeError: argument of type 'NoneType' is not iterable

I checked occurrences when it is called and can't find any piece of code
which calls it without path variable. Also if something is calling it, its
should break.

# Dummy extension that adds a delay after acquiring a lock.

# This extension can be used to test race conditions between lock acquisition.
