prevent segfaults when no document loaded
See the issue report for a description of the bug. The root cause is dereferencing of NULL pointers, specifically the priv->document member of EvWindow structures when no document is loaded. This commit adds checks for a NULL value of priv->document at all the points in the file shell/ev-window.c where this pointer was previously dereferenced without being checked. Fixes 357 (https://github.com/mate-desktop/atril/issues/357)
