[FIX] auth_session_timeout: add /longpolling/im_status as ignored url

auth_session_timeout [1] uses the time of the modification of the
session file to calculate the time of inactivity, but any edition in the
session file will change the time of modification of the file and cause
inexact time of inactivity.

The controller /longpolling/im_status is called several times (every 50
seconds) [2][3], so it is required taking it into account to avoid
modifying the time of modification of the session file, so it is
required adding /longpolling/im_status as a ignored url [4][5].
