plug-ins: WebP: save_dialog() before gimp_export()
As mentioned in issue #1777 (closed), exporting non-animated WebP images was only keeping the current layer. Mimick file-gif-save.c: display the encoding settings pop-up earlier so that gimp_export_image() can merge the layers unless "As Animation" is enabled. Call gimp_image_get_layers() directly in save_image() in case the layers were merged (for clarity because layers are used only for animations).
