Description of problem:
When searching for environment using exisiting organization/location as filtering criteria, it shows all environments. I've tried both name and id.

API, CLI and UI are affected.

First organization, all envs are listed:
> # hammer -u admin -p changeme environment list --search="organization=ldEfUWXqQE"
> ---|---------------------------------------
> ID | NAME                                  
> ---|---------------------------------------
> 2  | KT_EidanSPSEn_Library_lKlWziXRrT_78   
> 3  | KT_EidanSPSEn_SEIOiZvPNz_lKlWziXRrT_78
> 4  | KT_ldEfUWXqQE_Library_QWHvgzxtPg_81   
> 5  | KT_ldEfUWXqQE_MpMGDbtpLh_QWHvgzxtPg_81
> 1  | production                            
> ---|---------------------------------------

Second organization, all envs are listed:
> # hammer -u admin -p changeme environment list --search="organization=EidanSPSEn"
> ---|---------------------------------------
> ID | NAME                                  
> ---|---------------------------------------
> 2  | KT_EidanSPSEn_Library_lKlWziXRrT_78   
> 3  | KT_EidanSPSEn_SEIOiZvPNz_lKlWziXRrT_78
> 4  | KT_ldEfUWXqQE_Library_QWHvgzxtPg_81   
> 5  | KT_ldEfUWXqQE_MpMGDbtpLh_QWHvgzxtPg_81
> 1  | production

# Org id
> # hammer -u admin -p changeme organization info --name="EidanSPSEn"
> Id:                     48
> # hammer -u admin -p changeme environment list --search="organization_id=48"
> ---|---------------------------------------
> ID | NAME                                  
> ---|---------------------------------------
> 2  | KT_EidanSPSEn_Library_lKlWziXRrT_78   
> 3  | KT_EidanSPSEn_SEIOiZvPNz_lKlWziXRrT_78
> 4  | KT_ldEfUWXqQE_Library_QWHvgzxtPg_81   
> 5  | KT_ldEfUWXqQE_MpMGDbtpLh_QWHvgzxtPg_81
> 1  | production                            
                            
However, environment associated only with one organization
> # hammer -u admin -p changeme environment info --id=2
> Id:            2
> Name:          KT_EidanSPSEn_Library_lKlWziXRrT_78
> Puppetclasses: 
>    access_insights_client
> Locations:     
>    Default Location
> Organizations: 
>    EidanSPSEn
