Bug 4502: Catch software error if no active budget defined

Bug 4502: Catch software error if no active budget defined

TEST PLAN
---------
0) Back up your database.
1) In mysql client:
   > DROP DATABASE {your koha database name};
   > CREATE DATABASE {your koha database name};
   > QUIT;
2) Go to the staff client, and install all the default
   and optional things -- except patrons. :)
3) Log into staff client.
4) Create a patron -> New Patron -> Staff
5) Enter data and Save
6) More -> Set Permissions
7) Make superlibrarian
8) Log out
9) Log in as new superlibrarian
10) Acquisitions -> Budgets -> New Budget
11) Enter a non-active budget with some funds.
    -- Once saved, it should list in the inactive budgets.
12) Click on the name.
13) Click on one of the Planning submenu options.
14) Click the 'Submit' button in the Filter area.
    -- This should trigger the blow up.
15) Apply the patch
16) Repeat steps 12-15
    -- The kaboom is avoided and a nice message given.

NOTE: This does not solve all the problems in this ugly, ugly
      module area. It does solve the one thing it is meant to:
      that nasty kaboom.
