Page body text is not shown unless body text is given as well on a page

Subject of the issue

Page body text is not shown unless body text is given as well on a page.

Your environment

• Framework: 3.x.x
• Browser: Chrome - v59.0
• Ubuntu 14.04

Steps to reproduce

• Have a page both with a page body and body, see that they both show as expected.
• Have a page with only the page body - it doesn't show.

Expected behaviour

A page should be able to have a visible page body without a body being set.

Actual behaviour

Inputting only a page body means it won't display. If you were to want it to display, you would need to also input something into the body text, but this may not be wanted by the user.

adapt_framework/src/core/templates/page.hbs

Lines 19 to 29 in 1679cd9

	{{#if body}}
	<div class="page-body">
	<div class="page-body-inner">
	{{#if pageBody}}
	{{{compile_a11y_text pageBody this}}}
	{{else}}
	{{{compile_a11y_text body this}}}
	{{/if}}
	</div>
	</div>
	{{/if}}

I believe the issue is this above, just needs the first if removed.
