Bug 19913: Fix embedded HTML5 videos at the OPAC

Caused by
commit 752aef4593
Bug 18754: Translatability: Get rid of exposed tt directives in opac-detail.tt

A space is missing between 'source' and 'src'

Test plan:
Set  HTML5MediaEnabled  to OPAC
Put a video link to 856$u
See the OPAC detail page, tab video, click the video
=> Should play with this patch applied

Note that this does not affect intranet
