When invalid filenames are found during project-copy, the somewhat obscure (and non-localised) 'invalid element name' error is returned. Add a special case to handle this particular error and display something more descriptive to the user. Added a modal error handler for when this error is generated by clicking the 'copy' icon in the project list, instead of using the 'more' dropdown which opens a modal copy dialog bug: overleaf/sharelatex#908 Signed-off-by: Simon Detheridge <s@sd.ai>
