• Fixes System.InvalidOperationException when EditContext is configured

@jbomhold3
PR #201

• Removed thrown exception when using @ref and bool together.
• Allows @bind-IsOpen to allow users to mix @ref and manual operations.
• You may continue to use IsOpen without binding it. But any @ref changes will be ignored. Such as Hide, Close, Toggle.
• Obsolete IsOpen on BSDropdownToggle no longer required.
