[alisevych]

Description

Hide/remove additional empty tooltip shown for every field except "Timeout for class".
Wording corrections for tooltips on IDEA popup.

Expected behavior

   Need to hide/remove additional empty tooltip.

Wordings:

2. Code generation language:
   Now "Generating unit tests in Java"
   Expected "Generate unit tests in Java"

3. Mock strategy:
   Now "Do not use Mock frameworks at all"
   Expected "Do not use mock frameworks at all"

4. Mock static:
   Now "Don't use..."
   Expected "Do not use..."

Environment

IntelliJ IDEA, Android studio

Code generation language:
Now "Generating unit tests in Java"
Expected "Generate unit tests in Java" - agree

Mock strategy:
Now "Do not use Mock frameworks at all"
Expected "Do not use mock frameworks at all" - agree

As for Don`ts and do nots - if we want to make our UI more formal, it`s better to write tooltips without contractions. Otherwise, there is no big difference at all.
