You are specifying that the .bashrc file should be managed *before* the
directory check. This is exactly opposite to what you want. Switching to
the 'require' metaparameter will give you the evaluation order you want.
With that said, this is probably a poor approach overall. If you are
managing user accounts and the contents of their home directories then
almost certainly you should manage their home directories as well. If the
home directory were under management then you could either ensure it is
present, in which case you wouldn't need a test, or ensure it absent or
leave it unmanaged, in which case you could and should avoid attempting to
manage any contents.
If you insist on avoiding managing home directories themselves, and yet
managing their contents then Puppet's primary mechanism for conditional
action based on on machine state revolves around facts. You can use facts
for this even with only string facts. For example, it would be pretty easy
to write a custom fact that provided, say, a colon-delimited list of all
the subdirectories of /home, which your manifest code could then examine to
determine whether a particular home directory was present.
