Closing </tr> missing

[Jakobovski]

Thanks for the great free templates!

I noticed there is a closing <\tr> tag missing in a number(maybe all?) of the oxygen templates.

For example:
https://raw.githubusercontent.com/sendwithus/templates/master/templates/oxygen/invite.html

there are 22 opening <tr>s but only 21 closing </tr>s
