Fix list cell bugs - text when clicked and appropriate list icon

[lkarthee]

When a list cell is clicked - it behaves weird, it appends list into a single word.

After fix

Also the list column was using an GridColumnIcon.HeaderNumber icon when GridColumnIcon.HeaderArray icon is more appropriate.

I have done an npm install --force as normal install was failing due to incompatible react dependency. There after did a npm run build and tested the cell. Hopefully I have not missed anything.
