Get-Secret fails to retrieve some secrets listed by Get-SecretInfo

This should speak for itself:

````
PS❯ get-secretinfo | ? { $_.name -eq 'LeCab' } | select name,type

Name Type
---- ----
LeCab PSCredential

PS❯ get-secret -name LeCab
Get-Secret: The secret LeCab was not found.
````

In the affected vault, `Get-SecretInfo` lists 85 secrets, this failure occurs for 8 of them:

````
PS❯ get-secretinfo | ? { $null -eq (get-secret -name $_.Name -ea 0) } | select name, type

Name Type
---- ----
Enquête "Reconnaissance au travail" PSCredential
FileLocator Pro [LITE] PSCredential
International SOS PSCredential
LeCab PSCredential
OgoneVisaNo3DS PSCredential
Pick Go Pay APN key PSCredential
Samsung Galaxy A40 PSCredential
Windows 7 Ultimate PSCredential
