import decrypted pkcs12 private key

[tomholub]

after #3528 and #3529 we should enable this test (and see if there is something left to implement, this is untested functionality)

 // ava.default.only(
 // 'setup - s/mime private key',
 // testWithBrowser(undefined, async (t, browser) => {
 // const settingsPage = await BrowserRecipe.openSettingsLoginApprove(t, browser, 'flowcrypt.test.key.imported@gmail.com');
 // const key = {
 // title: 's/mime pkcs12 encrypted key',
 // filePath: 'test/samples/smime/human-unprotected-PKCS12.p12',
 // armored: null,
 // passphrase: 'test pp to encrypt unprotected key',
 // longid: null
 // };
 // await SetupPageRecipe.manualEnter(settingsPage, key.title, { submitPubkey: false, usedPgpBefore: false, key });
 // })
 // );

This test has remarks

 // todo - change to an "add key" instead of initial import test
 // todo - disable initial import of s/mime key

Are you sure we're ready to support S/MIME key as the primary user key?

I think very likely we're not ready to support S/MIME as the only user key. Just as a secondary to an already existing OpenPGP key that the user has.
