Handle `int` declared as `str` for `match.episode` on remaps

[BrutuZ]

What Happens

trakt-scrobbler silently crashes with the following entry to remap_rules.toml:

[[rules]]
match.title = "Doctor Who"
match.year = 2005
match.episode = "168"
match.season = 0
id.trakt_slug = "doctor-who-2024"
type = "episode"
episode_delta = -164

What Should Happen

Parser should gracefully handle a single episode declared as a string.

What changed

Added TypeError to the caught exceptions as groups contained in a part of the expression that don't match (m["end"]) return a NoneType (docs) which causes the int() operation fail instead of the mapping.

Added a commit to handle (ignore) the odd anonymous Plex sessions. Sometimes when streaming the session won't have a user name, it will look empty even on the server dashboard. Not sure if it's a side-effect of streaming via PlexKodiConnect but regardless, this is the expected behavior instead of raising an exception every few seconds
