Subject: [PATCH] Fix menu entry selection based on title

The get_entry_number_helper() function assumes that there could be a set
of entries identifiers in a variable (i.e: as used in the fallback case)
so iterates over the string until it finds a space to get the first id.

But this should only be done for indexes or entries id, since the title
can contain spaces. In the case of title, the complete string should be
used to select a given entry.

Resolves: rhbz#1654936
