Simplify pattern tests

- Stop using “adjust_pattern” and “exclude_path” as they're utility
  functions not relevant to testing pattern classes
- Cover a few more cases, especially with more than one path separator
  and relative paths
- At least one dedicated test function for each pattern style as opposed
  to a single, big test mixing styles
- Use positive instead of negative matching (i.e. the expected list of
  resulting items is a list of items matching a pattern)
