Do not select versions with a hyphen

... if the current version does not contain one. This is similar to
#1134.

`selectNext` currently allows these updates:
```
org.specs2:specs2-core:test : 4.5.1 -> 4.5.1-924020314
io.monix:monix-catnap : 3.1.0 -> 3.1.0-2156c0e
io.monix:monix : 3.0.0 -> 3.0.0-ec266e1
com.lihaoyi:ammonite : 1.6.7 -> 1.6.7-2-c28002d
com.lihaoyi:ammonite-ops : 1.6.6 -> 1.6.6-10-5fa74ab
com.lightbend.paradox:sbt-paradox-project-info : 1.1.3 -> 9-6845d95d
commons-httpclient:commons-httpclient : 2.0.2 -> 2.0-dev.20020705.071400
org.specs2:specs2-core : 4.2.0 -> 4.2.0-add90d25e-20180428143534
```
All of these look like a transition from a release version to a dynamic
version except that these version numbers don't use `+` but a `-` to
separate the dynamic part from the release version.
