Revert limit history range to current project

Revert the changes made by Issue #19945 (commit adbd088).

The api function history_get_event_from_row should not impose a
limitation for current project queries.

The original timeline issue, which #19945 was addressing, has now been
resolved in another way, see issue #21072.

Fixes: #21146
