query entries using a wildcard

[enriquezrene]

/time-entries endpoint has been modified to allow getting time entries by user id. The reports page is currently hitting the endpoint with no query parameters so we need to change the request to include a wildcard in order to get all the time-entries as follows:

/time-entries?users=*
