Setting `maxTestsPerMethod` is ignored

[alisevych]

Description

With new functionality:

• Generated test output size should be customizable #1235

When maxTestsPerMethod=1 is set test generation for ExceptionExamples is made with default settings.
There are 2 tests generated in a region, 3 tests generated per method.

To Reproduce

1. In ~/.utbot/settings.properties: set maxTestsPerMethod=1
2. Install latest build from main into IDEA 2022.2.3
3. Open UTBotJava project
4. Generate tests with 95% Symbolic execution for ExceptionExamples#initAnArray(int)

Expected behavior

There should be only 1 test per method generated.

Actual behavior

There are up to 3 tests per method generated, including 2 in the same region.

Reproducing

Steps to reproduce

1. Set maxTestsPerMethod=1 and maxTestsPerMethod=2
2. Installed the latest main in IDEA 2022.2.3
3. Generated tests with default setting on the following code:

public class CheckStatic {
    public int connect(Socket socket) throws IOException {
        socket.connect(new InetSocketAddress("0.0.0.0", 22));
        return 0;
    }

Actual result

The following tests were generated:

    ///region Test suites for executable CheckStatic.connect

    ///region FUZZER: SECURITY for method connect(java.net.Socket)
