spell: fix refresh of bar item "spell_suggest" when the input becomes empty (closes #1586)

Browse Source 
When the input is empty, length of string is zero: when sending zero to
function weechat_string_dyn_alloc, the function returns NULL and therefore we
return immediately instead of handling the empty input, which is a valid value.

The regression was introduced by the use of dynamic strings, commit:
