[python-pytrakt] fix season number in show_collection

[simonc56]

In Users, the show_collection() function fetches all collected seasons as seasons 1.

Here :

PyTrakt/trakt/users.py

Lines 375 to 376 in 8a6d4f1

	sh._seasons = [TVSeason(show=sh.title, **sea)
	for sea in show.pop('seasons')]

Same as:

• TvShow.seasons returns same season for each object #98

And the fix was:

• Patch 2 #100

fixes #76
