title: mockk, clearAllMocks or unmockkAll
body: <p>mockk 1.9.3</p>
  <p>In the test noticed if did static mock in previous test, the next test will be using same mock.
  Thought to do a reset at @After, but not sure which one to use clearAllMocks or unmockkAll.</p>
  <p>in <a href="https://mockk.io/" rel="nofollow noreferrer">https://mockk.io/</a></p>
  <pre><code>unmockkAll  unmocks object, static and constructor mocks
  clearAllMocks   clears regular, object, static and constructor mocks
  </code></pre>
  <p>but not clear what are the difference by <code>unmocks</code> and <code>clears</code>.</p>
  <p>e.g.</p>
  <pre><code>@Test
  fun test_1() {
      mockkStatic(TextUtils::class)
      every { TextUtils.isEmpty(param } returns true
  
      //test
      doSomeThingUsingTextUtils()
      // verify
      ... ...
  }
  @Test
  fun test_2() {
      // in this test it does not want the mocked stub behavior
  
  }
  </code></pre>
  <p>What it should use, <code>clear</code> or 'unmock`?</p>
