Fixes#2868, where pressing <shift-tab> then <ctrl-d> in history
completion (with > 256 items) would cause later items to disappear (and
cause a crash if you try to delete again).
Cause:
Scrolling to the bottom would fetch an additional 256 items (in addition
to the 256 that are fetched at first). Deleting causes the query to
re-run, but it only fetches the initial 256 items, so the current index
is now invalid.
Fix:
After deleting from the history category, call fetchMore until it has
enough rows populated that the current index is valid.
Override removeRows instead of removeRow.

Even though no item was deleted, it was manipulating the completion
model because beginRemoveRows was called before the exception was
raised.
This fixes that problem by moving the removal logic (and delete_func
check) into the parent model, so it can check whether deletion is
possible before calling beginRemoveRows.
Fixes#2839.
We get no last_atime limit at all otherwise:
qutebrowser.misc.sql.SqlException: Failed to prepare query "SELECT url, title,
strftime('%Y-%m-%d', last_atime, 'unixepoch', 'localtime') FROM
CompletionHistory WHERE (url LIKE :pat escape '\' or title LIKE :pat escape '\')
AND last_atime >= ORDER BY last_atime DESC": "near "ORDER": syntax error Unable
to execute statement"
We need to tell sqlite to convert the timestamps to localtime during
formatting, otherwise it formats them as though you are in UTC.
Also fix up a few uses of mktime.
For performance, re-introduce web-history-max-items.
As the history query has now become a very specific multi-part query and
history completion was the only consumer of SqlCategory, SqlCategory is
now replaced by a HistoryCategory class.
