TemplateURLService::GetDefaultSearchProvider() can sometimes return
nullptr.

This condition occurs more frequently on startup, before the
TemplateURLService has loaded the sqlite3 keyword table.

This condition is made more frequent (temporarily) since my recent
patch:
https://chromium.googlesource.com/chromium/src/+/ecae40df17fd8eaea5e45ad62eae8e5c906e3aa7

This CL fixes a crash by making RepeatableQueriesService check whether
the DSE is nullptr and gracefully early exiting in that condition.
