Crash: broken formula + clicking on the f(x) symbol

[Robin Lilian]

When I enter a formula like "2+", "2-" or "2*" and then click on the f(x) symbol to use a variable, the program crashes, telling me: "Parser Error: Unexpected end of expression on position [15 for -, 12 for "multiply", 2 for +]". For the record I did this in the little extra window called "Tool Settings" (or similar, I'm translating here). Valentina Version 0.4.2, Windows 8.1 32-bit.

I cannot replicate this issue. Attached is a video of entering 2+ then selecting f(x) symbol. The process works properly to completion. I have tried with different tools, etc.

I did notice that the 2+ is gone when completing the f(x) selection.

This issue occurred when I was editing an existing line (using the small window called "tool settings" that's always open). I haven't had the issue while creating lines either.

Funny thing, it seems like i have fixed this issue in the develop branch one day before. :)

Fixed issue #456. Crash: broken formula + clicking on the f(x) symbol.

The method FormulaFromUser throw an exception. In many places we don't catch the exception and i think this is wrong. New method TryFormulaFromUser was introduced for fixing situation. (grafted from a1a7dab0f21e7698812f44d50d7389fd36060eeb)
