Download openrc fail on Firefox if the project contains blanks

[Jose Castro Leon]

When downloading the openrc file or the ec2 credentials file on horizon of a tenant that contains blanks, on firefox the filename gets truncated up to the first space.

For example on a project called 'My Report' when downloading the openrc you are prompted to download a file called 'My' instead the expected behavior shown on IE or chrome 'My Report-openrc.sh'
