File completion not working in bash when using Hurl completion

[fabricereix]

Activating Hurl completion in bash (source completions/hurl.bash) enables to complete command-line parameters.
But at the same time, it removes file completion.

Without Hurl completion

hurl --verb<TAB>    => no completion
hurl test<TAB>      => hurl test.hurl

With Hurl completion

hurl --verb<TAB>    => hurl --verbose
hurl test           => no completion
