[e2e] Send ETH to an EOA using Ganache network on Android

[seaona]

Description
This PR adds an e2e testcase for Android with wdio/appium, using the Ganache network. The test is a Simple send flow to an EOA. For that, it's done the following:

• A Confirmations folder has been created for including the android e2e tests related to Confirmations
• A Confirmations suite has been created in order to run all confirmation related tests by using the flag --suite confirmations
• A Ganache server will be started whenever we use Ganache server is started from common steps
• The Ganache server will be stopped whenever we use Ganache server is stopped from common steps
• Ganache sets 10000 ETH by default to the generated accounts given the seedphrase we pass it. This seedphrase is defined on Accounts.getValidAccount()
  • It seems that the envar MM_TEST_ACCOUNT_SRP is not working and not correctly set. For this reason, running local tests we can add a seedphrase, in case the envar does not work seedPhrase: process.env.MM_TEST_ACCOUNT_SRP || 'phrase upgrade clock rough situate wedding elder clever doctor stamp excess tent',. Seems this is related to issue 762

Manual testing steps

• Connect an Android device to your computer / use simulator (see Android setup on readme)
  • You'll need to set the following vars

export ANDROID_HOME=/home/PATH_TO_ANDROID/Android/Sdk
export ANDROID_SDK_ROOT=/home/PATH_TO_ANDROID/Android/Sdk

• Open a terminal
• Expose the needed ports on your Android device
  • adb reverse tcp:8081 tcp:8081
  • adb reverse tcp:8545 tcp:8545 -- where ganache server runs
• Create the QA build
  • yarn setup
  • yarn start:android:qa
• Open another terminal
  • run yarn watch
• On the first terminal run the specific testcase yarn test:wdio:android --spec wdio/features/Confirmations/SendEthEOA.feature
• Notice you might need to add a seedphrase on the envar file and if it does not work, you can add it directly as indicated above
