behat date step causes whitespace error in single digit dates

[Rebecca Blundell]

There is a bug in the patch for Bug 1711277 - Add a step to check dates.
If the date is a single digit, e.g. today being 1 September, the date comes out as " 1 September 2017", when "01 September 2017" is what is being looked for on the page. This can be fixed by trimming the result.

I've also noticed that my i_should_see_date() function never runs the else statement as I'm passing in a default. I should clean this up, either by passing in null as a default format or by removing the else altogether.

Bug 1714408: Fix whitespace error in date format

Remove default date format and require it to be passed in.
Reinstate if statement which now runs if the date format is not found
in the langconfig.php file.

Also fix format in the modified_date.feature file so the test works
for single digit dates.
