[FIX] web: list/kanban: remove count limit if total clicked

Commit [1] adds a limit on the search_count done to get the total
number of records matching the domain in a list or kanban view
(displayed in the pager).
When the limit is reached (10000), a `10000+` is displayed as
total. Clicking on it performs a search_count to get the actual
number of records.

Before this commit, from that point, the count limit was set to the
total number of records. It means that if a record was created or
modified to match the domain in the meantime, and the user clicked
on the pager to see the next page (for instance), a `+` was again
displayed next to the previously fetched search_count, which looks
like a bug.

To prevent this from happening, this commit simply removes the
count limit once the user has clicked on the total.
