`read_yaml` should fail gracefully if yaml is malformatted

I got a rather ugly error message when my database was being built (did not save the traceback) which was due to a malformatted yaml file. I had to go through the traceback and add log.debug(filepath) to see which file was broken.

I suggest that in this function below

papis.nvim/lua/papis/papis-storage.lua

Lines 87 to 92 in f0054bb

    
           local function read_yaml(path) 
        
           	log.trace("Reading path: " .. path) 
        
           	local filepath = Path:new(path) 
        
           	local entry = lyaml.load(filepath:read()) 
        
           	return entry 
        
           end

we add

Catch the error: if read_yaml fails, just continue with the next one
A notify and log.debug event: notify the user which file failed

Edit: Found the error traceback here

Hey! Sorry, somehow this slipped under the radar! Fixing it now! I'm making a note to add a test to check for such failures. Thanks!

	local function read_yaml(path)
	log.trace("Reading path: " .. path)
	local filepath = Path:new(path)
	local entry = lyaml.load(filepath:read())
	return entry
	end
