fix(issue-stream): Change default query request (#59452)

this pr makes a slight change to the params we send to the backend. Now,
on the initial load where we are not waiting for saved searches, we will
delete the `query` query param if there is no specified query. in the
endpoint (https://github.com/getsentry/sentry/pull/59484) , it will
check if a query is sent and use it if it is. If not, it will go through
the process of checking the saves searches and use the default
"is:unresolved" if needed.
