Steps to reproduce:
1. Open attached project.
2. Open script named "NewBehaviourScript".
3. Add this line of code to the script: "NetworkClient.connection." and notice that external script editor (Visual Studio or MonoDevelop) suggest using "TransportRecieve" after a dot. However, word "Recieve" does not exist.

Expected result:
"TransportRecieve" should be "TransportReceive".

Reproduced with:
5.2.4f1, 5.3.4f1, 5.3.4p6, 5.4.0b18.

Cannot reproduce with 5.1.0f3, because it was not supported.
