Tests for Account class

[nicole-mcg]

Tests should be made for the Account class in file_server/web/account.py. The variable Account.directory can be changed in tests safely to run the methods in a test directory. This shouldn't need to be changed back, but should be set before any test with the Account class.

To get current directory for a python file:

import os, inspect
curr_path = os.path.split(inspect.stack()[0][1])[0]

The following tests should be included

• Creating the first account without an auth
• Generate an auth and confirm it is valid
• Create an account with a generated auth
• Create a session with an account and confirm session is valid, end the session and confirm session isn't valid, create a session with the same account and confirm the session is valid. Repeat with a different account used for the second session
• Create an account, then load the account into another variable and confirm the two are equal with ==

An example test can be found at file_server/file/__test__/test_snapshot.py
