[tracker/sam/tests-less-verbose] tests: Hide INFO and DEBUG messages by default

[Sam Thursfield <sthursfield src gnome org>]

commit 2c4b1ff5ad1359302e09d2e4abc866cf09067560
Author: Sam Thursfield <sam afuera me uk>

    tests: Hide INFO and DEBUG messages by default
    
    Tracker's DEBUG and INFO messages are very verbose -- thousands of lines
    each time you open a TrackerSparqlConnection, which some tests do many
    times. Let's hide the output by default, guarded behind the
    TRACKER_TESTS_VERBOSE environment variable which the functional-tests
    are already using.
    
    The size of the meson-logs.txt file reduces from 27MB to about 100KB
    with this change.
    
    Any really useful debug messages which are being lost after this change
    could be promoted to g_message() to ensure they are always logged.
