Equal Operator in the Issue navigator doesn't finds results for dates

Equal Operator ("=") in the Issue navigator doesn't find results for dates (Updated, Resolved, Target Start..)

Environment

Steps to Reproduce

1. Go to the Issue Navigator
2. Search for issues with updated dates for example
3. Check the date when a specific issue was updated
   •  
4. Query for issues which were updated on this specific date
   •  

Expected Results

Issue is found

Actual Results

Issue is not found in the results

Workaround

Use a timestamp in the date value specified to ensure the full day is included. e.g.

resolved <= "2017-08-28 23:59" instead of resolved <= "2017-08-28"

Alternatively, you can use the endOfDay() function. The function takes an input which is a relative date specifier, so it may not be as useful
