* I have a dashboard with two TSVB viz. One with the default (haven't applied it to the combobox) and one with the logs. The filter contains fields only from the logs index pattern
* When I am on the string mode and try to write my index, sometimes some of the chars are not added or they are deleted while typing, something with the denounce maybe?
* fix merge conflicts
* Does this PR also supports runtime fields? I created one from the editor and I see that I can select it
* fix UI issue
* If I create a viz with the string mode and a wildcard e.g. kibana_sample*, the index patterns are not communicated correctly to the dashboard.
* fix import/export refs for dashboard
* remove MigrationPopover
