Workaround cspell bug when cwd contains spaces

... or probably any chars that gets percent encoded when transformed to a URI. cspell translates the given path to a URI but the reporter has a bug where it compares the normal working dir with the percent encoded one. These two never match obviously and then cspell prints the complete percent encoded URI as the filename. We thus (a) teach the regex about these stdin filenames, (b) teach `is_stdin_filename` to always return `True` because the filename the reporter reports is not a filename that can found on the filesystem but an URI. If we return true, SublimeLinter core assumes the current view
