From: Wander Lairson Costa <wander@redhat.com>

The condition to check if the actions buffer needs to be resized was
incorrect. The check `self->size >= self->len` would evaluate to
true on almost every call to `actions_new()`, causing the buffer to
be reallocated unnecessarily each time an action was added.

Fix the condition to `self->len >= self.size`, ensuring
that the buffer is only resized when it is actually full.
