Problems with creating CredentialStore from scratch when directory path doesn't exist.

There are problems with creating CredentialStore from scratch when directory path doesn't exist.

How to reproduce

• /subsystem=elytron/credential-store=cs007:add(uri="cr-store://test/folderNotExist/keystorecs007.jceks?create=true", credential-reference= {clear-text=pass123}

  )

• /subsystem=elytron/credential-store=cs007/alias=newCs007:add(secret-value=Elytron)

You can see this error message

{
    "outcome" => "failed",
    "failure-description" => "WFLYELY00009: Unable to complete operation. 'ELY09504: Cannot write storage file '/home/hsvabek/securityworkspace/jboss-eap-7.1.0.DR7/standalone/data/folderNotExist/keystorecs007.jceks' for the store 'cs007''",
    "rolled-back" => true
}

When you execute repeatedly last command /subsystem=elytron/credential-store=cs007/alias=newCs007:add(secret-value=Elytron)
you get information about duplicate resource. It's mean the entry is in Credential Store (in memory) but not in file...

{
    "outcome" => "failed",
    "failure-description" => "WFLYCTL0212: Duplicate resource [
    (\"subsystem\" => \"elytron\"),
    (\"credential-store\" => \"cs123\"),
    (\"alias\" => \"newCs007\")
]",
    "rolled-back" => true
}

My suggestions for solutions of this two problems:

• try to create directory path
• when fails creating of CredentialStore file then we remove entry from memory too. It can be confusing have entry only in memory.
