Fix the serialization of grid-template-area.

Per https://drafts.csswg.org/css-grid/#serialize-template, we should
simplify the string:
1. Each null cell token is serialized as a single `.`.
2. Consecutive cell tokens are separated by a single space (U+0020 SPACE),
   with all other white space elided.
