[AND-65] Fix crash and improve error handling in poll creation.

[VelikovPetar]

🎯 Goal

• Fixes the crash happening when the user tries to create a poll with an empty value entered for "Multiple answers". We now disable the "Create" button, if the "Multiple answers" is checked, but the entered value is empty
• Add a "min" value of 1 for the "Multiple answers" field, because the createPoll operation will fail if the submitted value is 0.

🛠 Implementation details

• Add checks for empty switch fields when checking if the "Create poll" button is enabled
• Add minValue in the PollSwitchInput to include lower bounds validation

🎨 UI Changes

🧪 Testing

1. Open compose sample
2. Open channel
3. Open attachments and select poll
4. Enter poll question, answers, and toggle "Multiple answers"
5. Delete any input from the "Multiple answers" field
6. The "Create" button should be disabled, therefore preventing the crash
