Consumer search criteria not cleared/used when navigating to another …

…consumer - fixed

Fixes #1221

The search text will be cleared when switched to different cluster's consumers

• Breaking change? (if so, please describe the impact and migration path for existing application instances)
  Not a breaking change - issue fix just focuses on the search filter

What changes did you make? (Give an overview)
When switching between different clusters, I emptied the search field if the query param is not available

Is there anything you'd like reviewers to focus on?
No, please let me know if anything needs to be taken care of as this is my first open source contribution
