Upgrade the generated package.json to refer to 5.2.x

It is not obvious if the bug is related to this commit though.

@akkumar that was a flake in the CI and is not related to your PR. I have restarted that CI job. Thanks for updating these dependencies!

This is blocked on angular/angular-cli#9097

We should not update to TS 2.6 yet, there is an important issue with the language service which is not working anymore in TS 2.6 : angular/angular#21591

[akkumar]

Thanks @cyrilletuzi for bringing this one up.

For now - I have reverted the ts 2.6 change back to what it was ( 2.5.3 ) to avoid issues.

ng has been upgraded to 5.2.x though (with ts at 2.5.3 as before ). Because typescript is back to 2.5.3 it should also not be dependent anymore on angular/angular-cli#9097 - the issue that @clydin had referred to as well.

@filipesilva @Brocco - can you help check this one and get it in as ng 5.2.x would still be compatible with 2.5.x , I assume ?

Let me know your comments on the same.

[filipesilva]

LGTM as is, but yeah we're blocked on TS 2.6 for new projects until angular/angular#21591 is sorted.

[cyrilletuzi]

For info, even if angular/angular#21591 is not marked as fixed, I don't have anymore problems with TypeScript 2.6 and VS Code Language Service. I think the extension patched the issue inside itself, so it should be safe to upgrade to TS 2.6.
