Grails: with Tab code completion replaces only a part of config key

Provide grails application module.
Provide grails-app/conf/Config.groovy with a setting:
```
grails.views.gsp.encoding = "UTF-8"
```
In a grails-app/controllers/AnyController provide a reference to the option:
```
def sample = {
render "

$ConfigurationHolder.config.grails.views.gsp.encoding

"
}
```
Invoke completion (Ctrl+Space) in the middle segment of property reference, e.g. inside "views".
Completion shows all the rest segments of property name: "views.gsp.encoding".
Press Tab to select the item.
Result: the item replaces just a part before the 1st dot:
```
render "

$ConfigurationHolder.config.grails.views.gsp.encoding.gsp.encoding

"
```
The Tab should probably take into account that dot is a part of the value.

Create the Grails module described in the issue, including grails-app/conf/Config.groovy and the controller reference. Invoke completion inside the “views” segment and press Tab to reproduce the duplicated suffix. Done means the full dotted property value is replaced once, without appending “.gsp.encoding” a second time.
