Autocomplete does not insert correct word when requested with Ctrl+Space

[rthouvenin]

To reproduce: in a python editor, start typing something and when the word is long enough so that there should be only one auto-complete suggestion, invoke it with Ctrl+Space. For example, type enume and invoke the auto-completion. Because there is only one suggestion, the word is automatically completed. However the auto-complete menu opens anyway, and if I press Enter to validate and close it, the word is replaced with one where the beginning of the word is repeated. For example, in the case of enumerate, it is replaced with enumenumerate.

This does NOT happen when there is more than one auto-complete suggestion or when the auto-complete is automatically triggered when typing a dot, even if there is a single suggestion. In both these cases, the word is not automatically completed and pressing Enter correctly finishes the word.

Also, the problem occurs in latest Spyder 3.0.0dev, but not in the stable release that I have (2.2.5). In 2.2.5, the auto-complete menu does not open and the word is automatically completed to the single suggestion, which is I think the correct behavior (this is also what Eclipse does if I remember correctly). So it seems to be a regression. Will happily help fix it if given pointers.

Yes I have noticed this behavior and I can confirm, please @blink1073 take a look :-p
