Aesl file created in Thymio Blockly standalone cannot be used in Studio

Created by: ypiguet-epfl

If you create a program in Thymio Blockly, you save it as a .aesl file and you try to open it in Aseba Studio connected to the same Thymio node, Studio displays 1 scripts have no corresponding nodes in the current network and have not been loaded (sic). The source code is displayed in a new tab named thymio-II (not available) without the node-specific controls on the left of the window. Tested in 1.6, macOS 10.12, Thymio simulated in Playground. See also #670. Suggestion 1: if you can't match the node id, have a button to match the node by name if it's possible ("thymio-II" here). Suggestion 2: check the grammar in error messages.
