CSR Signing: uri_sans param ignored when use_csr_values=false

[mdgreenfield]

Describe the bug
When a CSR is signed using /pki/root/sign-intermediate the uri_sans param is ignored in favor of the uri_sans in the CSR even when use_csr_values=false.

Expected behavior
The uri_sans param when signing a CSR with use_csr_values=false should be used instead of taking the value from the CSR.

Environment:

• Vault Server Version (retrieve with vault status): 1.0.3
• Vault CLI Version (retrieve with vault version): 1.0.3

Although I'm using 1.0.3 the problem appears to affect 1.1.0 as well.
