if condition needs an else clause or it will crash

[Nicd]

If you use an if structure, you need to add an else clause, or nil will be added to the output, which will crash when the content is attempted to convert to string.

For example here, the empty else clause is required, to return an empty string instead of nil:

<%= raw(if ... do %>
  <%= ... %>
<% else %>
<% end) %>

Can you write a test case.

If it's possible to do a small one add it as a doc test here https://github.com/CrowdHailer/eex_html/blob/master/lib/eex_html/engine.ex#L26

Be good to have several test cases.

• two without an else clause, predicate true/false
• two with an else clause, again predicate true/false

If the PR is open with desired behaviour in tests it's really easy for someone to pick it up

This no longer occurs on the latest version for some reason so I'm closing this issue.
