Explore: typeahead and render performance improvements

- remove `edited` property of query objects
- query object semantics changes to be initial values only
- resetting or externally modifying a query is done via giving it a new
  react key, which replaces the row completely
- query changes while typing are sent up to Explore to be saved in a
  local property that is not part of the component state (prevent
  control circle)
- all Explore functions using the queries must access the local property
  for current values

- Lower debounce
- refactor suggestion selection
- make Portal pure
- use prev suggestions object if suggestions are the same
