"Describe Component" context menu always runs the command

[datho7561]

To reproduce the issue:

1. Set "openshiftToolkit.useWebviewInsteadOfTerminalView": true, in settings.json
2. Create a component
3. Right click the component, select "Describe"

I expect the webview to appear, as alluded to in the description of the openshiftToolkit.useWebviewInsteadOfTerminalView setting, but instead, the command is run in the terminal.
