Fix servlet name for GetApprovalStatus

In commit f91fc5c the
GetApprovalStatus was updated to use @WebServlet but the
servlet name was not set correctly and conflicted with
GenerateKeyPairServlet which was causing a problem for
TPS token enrollment with server-side key generation, but
for some reason the CI did not fail until recently.

Now the servlet name has been fixed so the problem should
no longer happen.
