GORM not recognizes executeQuery after domain class reloaded

At runtime, after change in hibernate mapped domain class, I get `String-based queries like [executeQuery] are currently not supported in this implementation of GORM` UnsupportedOperationException

I suppose that during class reloading, the hibernate's gorm implementation is somehow replaced with mongo's implementation.
It happens only when `compile :mongodb:3.0.3` is added to BuildConfig, even though any mongo datastore/domain is not configured. Removal of mongodb plugin solves problem. But I need mongodb in my actual app.

I attached logs with couple of comments what actions I took. [test4.txt](https://github.com/grails/grails-data-mapping/files/677444/test4.txt) If logs are not enough to tackle it, I am able to provide sample app.

My env:
Grails version: 2.5.4
java version "1.8.0_112"
plugins used:
```
plugins {
build(":release:3.1.2",
":rest-client-builder:2.1.1") {
export = false
}
compile ":wslite:0.7.2.0"
compile ":asset-pipeline:2.5.7"
compile ':cookie:1.4'

//runtime ":hibernate:3.6.10.19"
build ":tomcat:7.0.55.3" // or ":tomcat:8.0.22"
runtime ":hibernate:3.6.10.18"
compile ":taggable:1.1.0"
compile ":mongodb:3.0.3"
}
```

Start with the attached test4.txt logs and the reported class-reloading sequence in a Grails 2.5.4 application using hibernate and mongodb:3.0.3. Reproduce the failure where executeQuery becomes unsupported after a mapped domain class reload, then determine whether the behavior remains correct with the MongoDB plugin present but unused.
