Bugfixes in FindProbes

Two bugs fixed:

(1) previously, could not search for probes that have no genomic
annotation (the query was performing inner join on annotation
tables; replaced it with a left join).

(2) orphan experiments (not assigned to a study) were causing
trouble in CSV reports because platform id was previously
obtained from a study, not from the experiment as it should be.
Fixed that as well.
