Jonathan Druart 3f8a4cd2a1 Bug 17535: Fix search for reports by keywords
The commit cf90317112
    Bug 14435: Add the ability to store result's report
introduced a regression when searching for reports by keywords.
It also breaks tests in t/db_dependent/Reports/Guided.t

It's caused by the missing join on saved_reports.
The error says DBD::mysql::db selectall_arrayref failed: Unknown column
'report' in 'where clause'

Test plan:
Confirm that the tests are fixed and that you are able to search for
reports using the "keyword" input

This function returns a DBI statement handler from which the caller can
fetch the results of the SQL passed via C<$sql>.
If passed any query other than a SELECT, or if there is a DB error,
C<$errors> is returned, and is a hashref containing the error after this
manner:
C<$error->{'sqlerr'}> contains the offending SQL keyword.
C<$error->{'queryerr'}> contains the native db engine error returned
for the query.
C<$offset>, and C<$limit> are required parameters.
C<\@sql_params> is an optional list of parameter values to paste in.
The caller is responsible for making sure that C<$sql> has placeholders
and that the number placeholders matches the number of parameters.

# * This makes an effort to not break subqueries that have their own
# LIMIT specified. It does that by only removing a LIMIT if it comes after
# a WHERE clause (which isn't perfect, but at least should make more cases
# work - subqueries with a limit in the WHERE will still break.)
