[Github-comments] [geany] Avoid possible invalid memory access when activating plugin (#732)

[Jiří Techet]

It may happen (and happens on OS X) that plugin activation using
plugin_new() triggers some action which causes the tree view to
update. However, as the old plugin was freed before, the tree view
contains an invalid pointer to p which causes invalid memory access.

After freeing the old pointer, set the tree view value to NULL - the
plugin pointer is checked at other places for NULL value so it
doesn't crash.
