Fix Console.ReadLine in linux

[shargon]

Close #503

Please @superboyiii @cloud8little test it

It seems that there is a bug with linux and Console.Read

Bug POC:

Console.ReadLine(); // Show the output
Console.Read();  // Read only one char
Console.ReadLine(); // This doesn't show the output now :S

[cloud8little]

OK, I will have a test.

[cloud8little]

Test passed.

Verified this works on linux.

Looks good. But I doubt very much that Console.ReadLine() cannot be used in Linux. I didn't find related issues on Github. I think there must be something wrong with us.

I tried and search and I can't find a solution, after call Read or ReadKey, ReadLine starting to hide the key pressed in linux.

I will try to find the problem and fix it in dotnet source.

[shargon]

Wait, I know where is the problem

Please review it again, this is the real fix https://github.com/neo-project/neo-node/pull/516/files#diff-2ad153cafa6b784ceb93f0f6a668bcbdL27-L29

@shargon sure.

@shargon verified and test pass. I just want to know why ctrl+w worked before, and it does not work now.

It works before this PR, or it doesn't works time ago?

Before this PR, yes, ctrl+w worked.
