Adding a breakpoint then using "undo", then trying to re-add the breakpoint throws an error

[jmatostelerik]

Using undo after adding a breakpoint removes the breakpoint icon and debugger statement but does not remove the breakpoint that is registered with JsDebuggr, so trying to add it back causes the internally stored breakpoint to be removed. A workaround is to try to add the breakpoint twice. The 2nd time it will appear normally.
