Increase search rate for syncplan polling

[dosas]

Problem Statement

The timediff was increased to 5 minutes.
On 'fast' UIs this can lead to poll timeouts.

Solution

Increasing the search rate to 15 fixes this:
15 * 20 / 60 = 5

Can one of the admins verify this patch?

Can you please describe the issue you are seeing using the current implementation? Please also expand on what you mean by fast UI. I would like to understand better where you are coming from.

Okay.

As discussed in the related PR #15172 the sync interval was changed form 3 to 5 minutes. Allegedly because the navigation was (sometimes?) to slow and the task was executed before the polling (slow UI).

After I merged these changes in the downstream tests I had the issue that the polling went into a timeout because it stopped before the task was executed (fast UI).

So the fix is to increase the search rate so that the five minute mark is always reached.
