test-static-http.t: increase test coverage on filenames

Tracked files starting with a period in the name begin with '~2e' in the
store for the dotencode repository format, which is encoded as '%7E2e' in
URLs when accessing the repo over static-http.

The spaces in filenames are encoded with %20 in URLs.

See also issue 2566.
