do not change cursor position while replacing upload-placeholder

Browse source 
fixes #14695

Save caret position just before replacing the upload-placeholder.
replace upload-placeholder
Set caret position to the position in textarea as before replacing action.
Setting caret position considers the position before or after
placeholder and therefore the textlength of server-response to find the
right place.
