extended automation command to include Space

[benPearce1]

Automation commands produced in interactive mode always dropped the space from the automation command leaving it in a broken state if it is copied and pasted else where.

Fixes #295

Before:

> octopus project create
? You have not specified a Space. Please select one: empty
? Name test
? You have not specified a Lifecycle for this project. Please select one: Default Lifecycle
? You have not specified a Project group for this project. Please select one: Default Project Group
? Would you like to use Config as Code? No

Successfully created project 'test' (test), with lifecycle 'Default Lifecycle' in project group 'Default Project Group'.
View this project on Octopus Deploy: http://localhost:8066/app#/Spaces-822/projects/Projects-2142

Automation Commands:
octopus project create --name 'test' --group 'Default Project Group' --lifecycle 'Default Lifecycle' --no-prompt

After:

> octopus project create          
? You have not specified a Space. Please select one: Default
? Name test
? You have not specified a Lifecycle for this project. Please select one: Default Lifecycle
? You have not specified a Project group for this project. Please select one: Default Project Group
? Would you like to use Config as Code? No

Successfully created project 'test' (test), with lifecycle 'Default Lifecycle' in project group 'Default Project Group'.
View this project on Octopus Deploy: http://localhost:8066/app#/Spaces-1/projects/Projects-2141

Automation Commands:
octopus project create --space 'Default' --name 'test' --group 'Default Project Group' --lifecycle 'Default Lifecycle' --no-prompt
