Replaces always disabled context selection link

In the context selection dropdown, there is currently an always disabled
link to do more advanced filtering. The original intent was to open a
modal to do more advanced context selection. With the use of RBAC in a
previous bp, the Identity->Projects panel is always accessible. This
panel provides the entire project list for the user. We can just use
this to provide the larger project list to select from.
