Resource description of default repository is not good

[Jun Omae]

I noticed that get_resource_description with default repository returns u'Repository ' while working #10961. That result is not good….

>>> from trac.resource import Resource, get_resource_description
>>> from trac.test import EnvironmentStub
>>> resource = Resource('repository', id='')
>>> env = EnvironmentStub()
>>> get_resource_description(env, resource)
u'Repository '
>>> from trac.perm import PermissionError
>>> e = PermissionError('BROWSER_VIEW', resource, env)
>>> unicode(e)
u"BROWSER_VIEW privileges are required to perform this operation on Repository . You don't have the required permissions."

I think it should be u'Default repository' or u'Repository (default)'.

I like the former.
