Update LibrarySection.all() for more filtering/sorting and faster results

[JonnyWong16]

Description

Update LibrarySection.all() method to use LibrarySection.search() behind the scenes for more filtering/sorting options and faster results by taking advantage of pagination.

Breaking change:

• Sorting when using LibrarySection.all('title:asc') now requires the sort keyword argument (e.g. LibrarySection.all(sort='title:asc')).

Type of change

• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

What was wrong with the test when maxresults wasnt used?

[JonnyWong16]

.search() retrieves all items when maxresults is not specified.

container_start=0 and container_size=1 would just make 4 API calls with each call returning one item to retrieve all 4 movies.
