Bug 37292: Add an index on oauth_access_tokens.expires

This patch adds a needed index to the column.

To test:
1. On a fresh KTD, run:
   $ ktd --shell
  k$ koha-mysql kohadev
   > SHOW CREATE TABLE oauth_access_tokens;
=> FAIL: There's no 'KEY' entry for the `expires` column
2. Apply this patch
3. Run:
  k$ updatedatabase
=> SUCCESS: A message tells the index was added
4. Repeat 1
=> SUCCESS: The index was actually added to the DB
5. Run:
  k$ reset_all
6. Repeat 1
=> SUCCESS: The index is created at install time too!
7. Run:
  k$ updatedatabase
=> SUCCESS: Nothing explodes, no message about index being created
8. Sign off :-D
