Reminder to remove flag from flask test

[Lykhoyda]

Describe the bug
The test "should not add network" is skipped in the Flask version due to the error in the latest metamask update (v10.24.0). The bug is reported to the metamask team. We need to remove the check to skip the test in the flask once it will be fixed in the future version.

To Reproduce
Steps to reproduce the behavior:
Run tests with flask v10.24.x and remove the flag in "should not add network"

if (this.browser.isMetaMaskFlask()) {
      this.skip();
    }
