Subject: Enterprise phone lookup should return consistent result...

regardless of requested projections.

In order to rewrite the cursor returned from the corp CP2, certain columns
are needed to compute other columns.
(e.g. PHOTO_URI requires _ID and PHOTO_FILE_ID).

This CL fixes that by always requesting all columns to the corp CP2.
Now rewriteCorpPhoneLookup() shrinks down the projection.

Bug 19545750
