Issue archive page pagination is not disabled when items per page number doesn't exceed the limit

[Vitaliy-1]

Pagination doesn't work as expected because $prevUrl and $nextUrl are always not empty due to whitespaces. For example, it can be tracked in this line: https://github.com/pkp/healthSciences/blob/master/templates/frontend/components/pagination.tpl#L20
Think, the easiest way is just to trim these variables on assigning: pkp/ojs#1942
Although, there can be more variables that should be treated like this.

The adjustment should be made for all themes using this code, including default, bootstrap3, healthSciences; already applied the fix to the latter, although it can be not full.

Ok, it looks like this change isn't necessary for the default templates. At the moment, we use {url|assign... which doesn't introduce white space. And when Smarty v3 comes in, it looks like Alec handled it without introducing whitespace: https://github.com/pkp/ojs/pull/1782/files#diff-a1ed6d61c23c3df405232fd4b17b91aeR45

So I've flagged up the issue in the Bootstrap3 theme (we'll have other adjustments to make to fit the Smarty v3 syntax). Otherwise we should be good to go.

Nice find here @Vitaliy-1. I'll close the OJS PR but let me know if you think I'm wrong.
