Mitigate ordering dependency between Facets and SearchBar (#401)

Facet retrieval isn't enabled until the Facets component is mounted and
initial search happens when the the SearchBar component is mounted,
creating an ordering dependency between the two components, if one
wishes for facets to be present for an initial search.

The location permissions check in
4afecdd mitigates this issue by
performing the search asynchronously; this commit makes the code path
also asynchronous in browsers that don't support the permissions API.
