SharedNetworksTableComponent unit tests are unstable and often cause timeouts

I run the UI unit tests manually using debug mode with chrome. The SharedNetworksTableComponent unit tests often fail with the error message similar to this:

SharedNetworksTableComponent > should display error about wrong query params filter
Error: Timeout - Async function did not complete within 5000ms (set by jasmine.DEFAULT_TIMEOUT_INTERVAL)
    at <Jasmine>

They usually fail together, but sometimes only one test. The test above failing is just an example. The issue is not limited to this test.
