ui: change default path fallback mechanism (issue4796)

The previous paths API code always fell back to the default path. This
was wrong because if a requested path doesn't exist, that should error.
Only if no path was requested should we fall back to the default.

As part of implementing the test case for issue 4796, it was discovered
that the "repository does not exist" error message raised by
localrepository.__init__ wasn't being seen because the paths API
validates paths before localrepository.__init__ was being called.
The exception and error message from localrepository.__init__ has
been introduced to getpath(). This necessitated rewriting
expandpath() both to catch the exception and to have proper
default fallback.

This code is more complicated than I'd like. But making all tests pass
was a big chore. As more code moves to getpath(), there will likely be
opportunities to improve things a bit.

test command parsing and dispatch

Missing arg:

  $ hg cat
  hg cat: invalid arguments
  hg cat [OPTION]... FILE...
  
  output the current or given revision of files
  
  options ([+] can be repeated):
  
   -o --output FORMAT       print output to file with formatted name
   -r --rev REV             print the given revision
      --decode              apply any matching decode filter
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
