Bug 1494937 [wpt PR 13259] - accname: tweak two tests for clarity, a=testonly

Automatic update from web-platform-testsaccname: tweak two tests for clarity

Don't use the same value for the title attribute for multiple elements
within a single test. Doing so makes it harder to tell which title was
used for the name computation.
