activate() does not fail despite an error in @venly/connect

[sinolopes]

The activate function is supposed to fail if an error is made by a child component/function call.

example on the metamask connector:

1. launch the activate function
2. metamask opens with the connection request
3. the connection is refused which causes an error
4. in the connector we therefore execute: this.actions.startActivation()

the variable isActivating is reset to false, so we can run the activate function even after refusing the connection

example on the venly connector:

1. launch the activate function
2. venly connector open a window with the connection request
3. we close the new window
4. this causes an error in @venly/connect/dist/connect/Flows.js

This does not cause an error in the connector, so we are blocked because if the variable isActivating remains true we cannot execute the activate function.
