[SIGNED-OFF] Bug 11137: fix certain types of searches run using QueryParser

QueryParser was loading redundant search aliases, which in turn resulted
in certain queries involving two or more clauses joined by a Boolean
operator getting parsed in correctly.

To test:

[1] Enable QueryParser.
[2] Arrange your database so that some some bib records contain
    the keyword 'history' while a smaller subset contain
    both 'history' and 'earth'.  (The exact words used don't
    matter.)
[3] Run the following search from the OPAC global search bar:

    kw:history && kw:earth

[4] Observe that the records that are returned include *all* bibs
    in the database with the keyword 'history'.  In other words, the
    restriction  that the records must also contain 'earth' is not
    observed.
[5] Apply the patch and rerun the search.
[6] This time, the results that are returned should include only those
    that contain both 'history' and 'earth'.
[7] Verify that prove -v t/QueryParser.t passes.

Passes test plans, all tests and QA script.
Also checked the db_dependent/Search.t tests.
Tried some other searches, all seems to be working correctly.
