Bug with autocompleteProvider in <encounterProviderAndRole/> tag

The <encounterProviderAndRole/> using the autocompleteProvider="true" providerMatchMode="ANYWHERE" yields the names of all provider roles, even if providerRoles parameter is specified.

To reproduce...

1. Log into OpenMRS and ensure that no user has more than one provider account. System Administration --> Manage Accounts
2. Create a new HTML Form. System Administration --> Advanced Administration --> Manage HTML Forms --> New HTML Form.
3. Give it a name "James", Version of "1" and select an encounter type.
4. Define the form with the following HTML:

   <htmlform> 
   <encounterDate/>
   <encounterLocation/>
   Doctor: <encounterProviderAndRole encounterRole="2" providerRoles="1" autocompleteProvider="true" providerMatchMode="ANYWHERE" />
   Nurse: <encounterProviderAndRole encounterRole="2" providerRoles="3" autocompleteProvider="true" providerMatchMode="ANYWHERE" />
   <submit/>
   </htmlform>
   

5. Save the form, and preview it. Search for "ja" and see that it shows a doctor and a nurse name (the same results) in both provider search boxes.

This happens on the web demo too.
