Initialize `$envvars_array` to an empty list.

With strict debugging, i.e. `Set-PSDebug -strict`, execution of export.ps1 will
report the following error:

```
The variable '$envars_array' cannot be retrieved because it has not been set.
At C:\path\to\export.ps1:15 char:1
+ $envars_array # will be filled like:
+ ~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (envars_array:String) [], RuntimeException
    + FullyQualifiedErrorId : VariableIsUndefined
```
