ArgumentOutOfRangeException is thrown on paste when the masked input is unloaded and loaded again before that. Reproducible only in NoMask scenario (Mask="")

You can reproduce the issue using the following steps:

    1. Define a RadMaskedTextInput control
    2. Enter some text in the control
    3. Copy the text (the copy source is not important you can copy whatever you want)
    4. Remove the masked input from the visual tree
    5. Add the masked input back in the visual tree and reset its Value property, then focus the control manually (ex: using its Focus() method).   
    6. Paste the text from the clipboard without clicking on the control.

Fixed in LIB Version 2016.1.404.
