[SLO] Sometimes search erroneously reports back empty list of SLOs

[jloleysens]

Kibana version:
8.10.1

Describe the bug:
When searching for SLOs using KQL sometimes the request gets issued and does not contain the full query.

For example:

Input text as displayed in UI is: slo.name : *Kibana*
But request is: <base-url>/api/observability/slos?kqlQuery=slo.name%20%3A%20*K&sortBy=status&sortDirection=desc&page=1

Only when pressing enter again does the full query get sent as:

<base-url>/api/observability/slos?kqlQuery=slo.name%20%3A%20*Kibana*&sortBy=status&sortDirection=desc&page=1

How to reproduce:

1. Type text in to the search bar and press enter to search
2. See the following result:

This is a flaky issue, but happens often enough that it should be considered a bug.

Expected behavior:

Should run the query that is present in the search bar
