Library section lookup clobbered when multiple libraries have the same title

[JonnyWong16]

Describe the Bug

_sectionByTitle gets clobbered when there are multiple libraries with the same title. The returned library could be unexpected to the user.

https://github.com/pkkid/python-plexapi/blob/4780026a73af06af8801dada01f249ef6f8bb8db/plexapi/library.py#L51

Code Snippets

# Library 1: title = Movies, sectionID = 1
# Library 2: title = Movies, sectionID = 2
# Library 3: title = TV Shows, sectionID = 3

# ambiguous library name, returns library 2
plex.library.section("Movies")

# unambiguous library name, returns library 3
plex.library.section("TV Shows")

# The only way to return library 1 is by ID
plex.library.sectionByID(1)

Expected Behavior

Maybe raise a warning (non-breaking change) or exception (breaking change) indicating at the library title is ambiguous and directing the user to use sectionByID() instead.

Additional Context

The current behaviour returns the last library (highest sectionID) with the same title.
