Resolving symbol doesn't support resolving by short name

[bhp-work]

First of all thank you so much team for the ready to use tradingview implementation. This is really great.

It throws 'cannot resolve symbol' when compared. Also I am not sure if this issue is with all or just me because I did some code changes and not really sure if that has cause the issue. Please try to reproduce and check. If you are not able to reproduce then please close the issue :)

I guess we have to set ticker property here as well. Would you like to make a PR?

See https://github.com/tradingview/charting_library/wiki/Symbology#ticker.

Also, we can solve the issue by search not by just full_name, but by the name either.
