Current behavior
When the date format contains whitespace characters, changing the text in the input clears the value of the input. This happens only when "showTime" is true.

Expected behavior
The text won't be cleared if the date format contains whitespace characters.

Minimal reproduction of the problem with instructions
STEPS TO REPRODUCE
Pre-action: Set this format for p-calendar: M dd, y (Sep 19, 18) .

1. Select a date from the date picker.
2. Click into the input, and modify the day to a valid value (e.g.: Sep 19 to Sep 18) and close the date picker.
   Actual result: The input is cleared.

I found the reason in your source code in calendar.ts#parseDateTime:
This is the point where you should modify the code:
let parts: string[] = text.split(' ');
In my case, parseDate method gets only 'Sep' in the first parameter (this.parseDate(parts[0], this.dateFormat)).
