Allow UTBotPython to proceed test generation till timeout when function has full annotation

[tamarinvs19]

Description

When we have only one type we can use all time to generate tests for this annotation instead of splitting time for other inferred annotations (and wasting time).

Expected behavior

If function is annotated and all types are full (no one missed part, no one typing.Any, no one generic, no one protocol) UtBot will proceed test generation till timeout.

Potential alternatives

In future we can make option for this feature and add different modes of test generation:

• cover all branches and exit
• use all possible time
