Tests: the colour-font PDF test counts only text objects, not the random file ID

Browse Source 
pdf_real_text_draws_svg_glyphs_as_art_and_keeps_their_characters counted
every line containing Tj or TJ. The file ID in the trailer and the XMP is
base64 derived from the timestamp, so about one run in a hundred it spells
one of them and the test saw two extra lines (main CI, 5c1185dd). Only
lines that begin a text object count now.
