Reindexing all spaces aborted on the first disabled space. The storage
provider answers with "not found" for the root of a disabled space, so
the tree walk failed and the error took the whole run down, leaving the
remaining spaces unindexed.
Skip disabled spaces and log them instead, they have to be indexed again
once they have been enabled.
