highlighter: check for accents key

Browse Source 
This is actually a work around for a broken installation. the dict p
should always contain the accents key (see `airline#themes#patch()`
function, that adds missing accents). So even if the theme does not
define the accents key, it should always exist.

However, an error while evaluating the statusline is extremely annoying,
so add some safeguards here and skip the following for loop.
