https://github.com/w3c/csswg-drafts/issues/4475 resolved to try to stop
including implicit tracks in the resolved value of grid-template-columns
and grid-template-rows.

This implies that the resolved values will have less information now,
which affects lots of tests. I have edited them depending on the case:
 - When the size of the track was irrelevant (e.g. just checking whether
   some value was syntactically valid), I have just updated the expected
   value.
 - When the size of the track was relevant, but it wasn't important for
   the tracks to be implicit, I have made them explicit in order to get
   the same value.
 - When the test was about the sizes of implicit tracks, I have added
   new checks for the size and position of the grid items.
