The patron search "Clear Form" button clears the value
from the Home Library selector and sets it to undefined.
This can cause some strange results for subsequent
searches, where the workstation ou can get inserted
unintentionally.
This branch changes the Clear Form input from a reset button to
just a button, so the clearForm() function does all the work.
The clearForm() function is changed to set the Home Lib to cons
and the Include Inactive to true, so a reset results in the broadest
search possible.
Testing Notes:
1. Clear browser pref for eg.circ.patron.search.ou in admin ->
workstation -> stored preferences.
2. Load patron search.
3. Press clear form. (Home library gets cleared)
4. Add some search args and perform a search that returns some patrons.
5. Open a patron.
6. Click on patron search in upper right corner to return to results.
7. Note that home library is now set to workstation ou.
After fix applied.
Perform above steps, but note that clear form sets Home Lib to cons,
and doesn't unset Include Inactive.
