KointTestRule doesn't catch potential exceptions in tests

[mottljan]

Description
When the exception is thrown in the JUnit test which uses KoinTestRule, it fails other tests as well because the exception is not caught in the rule.

To Reproduce
I created a simple demo to illustrate the issue.

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
class KoinTest {

    @get:Rule
    val koinRule = KoinTestRule.create {}

    @Test
    fun first() {
        throw Exception()
    }

    @Test
    fun second() {}
}

Second test should pass but fails with java.lang.IllegalStateException: A KoinContext is already started.

Here is the implementation in the KoinTestRule.

override fun apply(base: Statement, description: Description): Statement =
            object : Statement() {
                override fun evaluate() {
                    _koin = startKoin(appDeclaration = appDeclaration).koin
                    base.evaluate()
                    stopKoin()
                    _koin = null
                }
            }

base.evaluate() throws an exception from the test which is not caught and Koin is not properly stopped. Solution is to catch the exception or extend TestWatcher instead of TestRule because TestWatcher already handles exceptions internally.

Koin project used and used version
koin-test version 2.1.5
