`updateSbtClassifiers` tried wrong bintray doc and src address.

[Chung Cause]

## steps
Use IDEA refresh project via sbt-shell with "Download sbt and plugin src and doc" checked.


## problem
IDEA executed `updateSbtClassifiers` and failed to download src and doc because of wrong uri:
```
https://dl.bintray.com/cuzfrog/maven/com/github/cuzfrog/sbt-tmpfs_2.12_1.0/0.3.0/sbt-tmpfs-0.3.0-sources.jar
```

and it did not try
```
https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/com.github.cuzfrog/sbt-tmpfs/scala_2.12/sbt_1.0//0.3.0/docs/sbt-tmpfs-javadoc.jar
```
## notes

use `reload plugins` then `updateClassifiers` worked around this.
sbt 0.13.16 works fine without this problem.


sbt version: *1.0.0*

Hi,

This sounds like something specific to IntelliJ, if so it might be better to report to them directly.

`updateSbtClassifiers` is an sbt phrase, IntelliJ uses it.

This problem does not occur in sbt 0.13.16, that means under previous version `updateSbtClassifiers` is fine.

Hi Eugene.
This is not specific to intellij. `updateSbtClassifiers` is just broken in 1.0 https://github.com/sbt/sbt/issues/3432.

I reported it to intellij just to complete the circle https://youtrack.jetbrains.com/issue/SCL-12788
