memory leak in spell checker plugin

[Sergey Basalaev]

Spell checker plugin does not free resources after document is closed.

Steps to reproduce:

1. Open gedit
2. Enable spell checker plugin
3. Open document in gedit, notice that memory usage of gedit increased (by approx. 10 MB for me)
4. Close document, notice that memory usage is not decreased
5. Open the same document again, notice that memory usage of gedit increased again

After repeating steps 3-5 a couple of dozens times gedit consumes much of RAM.

This also works if spellchecker is the only enabled plugin so this is not an issue of another plugin. And if the spellchecker is disabled then I unable to reproduce this behavior (after opening/closing about 50 files memory usage increased by just ~0.5 MB).
