Explain the environment

• Chaos Genius version: 0.5.0

Current behavior

Port number changes and user might not realise how it changed and mistaking that they put wrong port

Expected behavior

should not change without user's explicit editing

Screenshots

Additional context

• occurs on both Datasource add form and Email channel add form
• The port number input field is of input type "number" and this is because number fields behave in a way that whenever someone presses up/down key or scrolls while focus is on field it will decrease or increase the value
